Abstract
A continuous two-channel cystometric method (CTCHM) for monitoring bladder function in women suffering from urinary incontinence is described. The purpose of this technique is to provide a cheap minimal evaluation for patients who cannot afford an electronic examination. Through the CTCHM it was possible to diagnose detrusor instability in 11.1% of 108 patients. This method has proved to be useful in a developing country, where an electronic urodynamic evaluation is expensive or often is not available.

Editorial Comment: This is a description of a new technique for two-channel cystometry using non-electronic equipment. With the simultaneous measurement of the bladder and rectal pressures and the continuous monitoring of the two fluid columns the detrusor (substracted) pressure is easily obtained. All the components of this technique are readily available in any hospital or clinic where intravenous infusions are done. What needs to be done is to compare this technique with standard multichannel electronic cystometry. This study is under way by the authors. If this technique proves to allow an accurate measurement of detrusor pressure and thus the detection of detrusor instability preoperatively, surgery may be chosen more wisely in those developing countries where expensive multichannel urodynamic evaluations are not readily available or are not available at all.
